Conventional farming is a new area of research in developing countries. It is rooted in industrial agriculture andfocuses on production as heavily. It demands a high amount of chemical fertilizers. The research follows a case study under the interpretive paradigm using multiple sources of evidence such as interviews, observations, and surveys ofthe literature. Usual to most conventional practices, the local inbreeds of crops are replaced by high yielding varieties of crops. One of the main advantages of conventional farming is the application of a higher amount ofagricultural inputs. The study has shown that the availability of transport made it easy to reach products to the market and has contributed to increasing the income of the farmers. Inadequate knowledge of the use of fertilizers and pesticides results in the origins of new diseases in crops is a major challenge of conventional farming. This research concludes that commercial organic farming can be an alternative to conventional farming. The finding shows the need for agricultural training and capacity building of farmers and also the need to provide subsidies so that farming will be more lucrative.

Abstract. In this study we assessed the C : N : P ratios in soil and soil microbial biomass subject to conventional farming and three different organic farming practices. The results showed that microbial biomass was P-limited in soils subject to conventional farming and to organic farming with alfalfa green manure. Organic farming with compost amendment showed the best results in terms of microbial biomass carbon, nitrogen and phosphorus (CNP).

AbstractOrganic farming is increasing in Finland, and organic farms have become larger than conventional farms, on average. As the structural change has been rapid, farmers need a broad range of new competencies to manage their farms, ranging from agronomic skills to advanced technology, labor management, and marketing skills. In this study, the characteristics of organic and conventional farms and farmers were assessed, with special focus on management practices and future development plans on organic farms. The study was based on telephone interviews of a sample of active farmers who applied for agricultural subsidies in 2014. The data consisted of 3045 farmers; 312 of them practiced organic farming and 2733 conventional farming. The data were analyzed using multivariable logistic regression. Having beef production as the main production line, having plans to develop farm production in the next 5 years, considering farm management as very important, and frequently experiencing mental strain because of farm management were significant predictors for being an organic farmer. Dairy production was less frequently organic compared to crop production. Nearly half (42%) of organic farmers planned to make changes in their farming, most commonly expanding their production. Thus, competence for managing the farm operation becomes more crucial, which increases the need for training and management consulting services. Organic farming may increase with both farm successions and new entrants joining the farming sector. Special attention should be paid to supporting these new entrants without farm-family background.

Conventional agricultural systems increase per-area food production, but deplete natural resources and degrade both crop and environmental quality. Many of these concerns are addressed by sustainable agricultural systems, integrated pest management, biocontrol, and other alternative systems. Environmental and social concerns have escalated the need for alternative agricultural systems in the last decade. One alternative, the organic farming system, substitutes cultural and biological inputs for synthetically made fertilizers and chemicals for crop nutrition and pest management. Practices used for crop and pest management are similar during transition from conventional to organic farming systems, but produce is not certified to be organic during the transition period. During the transition from conventional to organic farming, growers may face pest control difficulties and lower yields when conventional practices are abandoned. The objectives of this paper are to 1) give an overview of the reasons for converting to organic farming and the challenges that growers face during the transition period, 2) outline some potential strategies for crop, soil, and pest management, and 3) list guidelines and recommendations for pest management during the transition to organic farming. Implementation of crop and pest management practices depends on geographical location, climate, available onsite resources, and history of the land. During transition, growers rely on cultural mechanisms and on organic and mineral sources to improve soil fertility, to build a population of natural enemies to suppress pest populations. Pest management practices during the transition period that reduce pest populations to economically manageable levels include crop rotation, cultivation, cover crops, mulches, crop diversification, resistant varieties, and insect traps. These practices also enrich the soil biota and increase crop yields before produce is certified organically grown.

Economics of a farming system is the key determinant of its sustainability. Organic and conventional farming systems are two distinct types of production systems having contrasting farm management practices and output price as well. Furthermore, organic farming system is promoted for environmental protection and conventional farming system is cursed for the environmental degradation. The present study was conducted to compare the economics of organic and conventional vegetable production in Kathmandu valley. Thirty farmers each involved in commercial organic and conventional vegetable farming were selected randomly for the study. Data were collected through survey method using semi-structured questionnaire. The estimated per ropani per year cost of cultivation of vegetables in the organic farm (NPR 69,170) was lesser than in conventional farm (NPR 1,00,562). The gross return per ropani in a year in the organic vegetable farm (NPR 1,01,536) was significantly lesser than from conventional farms (NPR 1,35,747). Benefit to cost ratio (BCR) was higher in organic farm (1.47:1) in comparison to conventional farm (1.35:1). This study revealed that organic vegetable farming was more profitable than conventional vegetable farming in Kathmandu valley. To expand commercial agriculture: quality inputs, input and output price stability, co-operative or corporative marketing should be promoted.

The impact of organic, compared with conventional, farming practices on N leaching loss was studied for Danish mixed dairy and arable farms using an N balance approach based on representative data. On mixed dairy farms, a simple N balance method was used to estimate N surplus and N leaching loss. On arable farms, the simple N balance method was unreliable due to changes in the soil N pool. Consequently, the Farm ASSEssment Tool (FASSET) simulation model was used to estimate N surplus, N leaching loss and the changes in the soil N pool.The study found a lower N leaching loss from organic than conventional mixed dairy farms, primarily due to lower N inputs. On organic arable farms, the soil N pool increased over time but the N leaching loss was comparable with conventional arable farms. The soil N pool was increased primarily by organic farming practices and incorporation of straw. The highest increase in the soil N pool was seen on soils with a low initial level of organic matter. The N leaching loss was dependent on soil type, the use of catch crops and the level of soil organic matter, whereas incorporation of straw had a minor effect. N leaching was highest on sandy soils with a high level of soil organic matter and no catch crops. The present results stress the importance of using representative data from organic and conventional farming practices in comparative studies of N leaching loss. Lack of representative data has been a major weakness of previous comparisons on N leaching losses on organic and conventional farms.

Organic agriculture is often perceived as more sustainable than conventional farming. We review the literature on this topic from a global perspective. In terms of environmental and climate change effects, organic farming is less polluting than conventional farming when measured per unit of land but not when measured per unit of output. Organic farming, which currently accounts for only 1% of global agricultural land, is lower yielding on average. Due to higher knowledge requirements, observed yield gaps might further increase if a larger number of farmers would switch to organic practices. Widespread upscaling of organic agriculture would cause additional loss of natural habitats and also entail output price increases, making food less affordable for poor consumers in developing countries. Organic farming is not the paradigm for sustainable agriculture and food security, but smart combinations of organic and conventional methods could contribute toward sustainable productivity increases in global agriculture.

Water contamination is often reported in agriculturally intensive areas such as the Indo-Gangetic Plain (IGP) in south-eastern Asia. We evaluated the impact of the organic and conventional farming of basmati rice on water quality during the rainy season (July to October) of 2011 and 2016 at Kaithal, Haryana, India. The study area comprised seven organic and seven conventional fields where organic farming has been practiced for more than two decades. Water quality parameters used for drinking (nitrate, NO3; total dissolved solids (TDS); electrical conductivity (EC) pH) and irrigation (sodium adsorption ratio (SAR) and residual sodium carbonate (RSC)) purposes were below permissible limits for all samples collected from organic fields and those from conventional fields over the long-term (~15 and ~20 years). Importantly, the magnitude of water NO3 contamination in conventional fields was approximately double that of organic fields, which is quite alarming and needs attention in future for farming practices in the IGP in south-eastern Asia.

The aim of this study was to evaluate, in the field, the soilrespiration and bulk density underconventional and organic farming plots. The evaluations were made in different plots established as conventional farming system and organic farming system with six, nine, twelve, fifteen, eighteen and twenty one months old. Plots were divided in four transects (subplots) and ineach subplot were evaluated soil respiration, bulk density and porosity. The soil respiration was significantly greater in organic farming system with fifteen, eighteen and twenty-one monthsold as compared with conventional farming. Soil bulk density decreased fifteen months afteradoption of organic system. Theresults showed that the adoption of practices in organic farming plots increases microbial activity and decreases soil bulk density over time.

To date, there has been little research into the role of microbial community structure in the functioning of the soil ecosystem and on the links between microbial biomass size, microbial activity and key soil processes that drive nutrient availability. The maintenance of structural and functional diversity of the soil microbial community is essential to ensure the sustainability of agricultural production systems. Soils of the same type with similar fertility that had been under long-term organic and conventional crop management in Canterbury, New Zealand, were selected to investigate relationships between microbial community composition, function and potential environmental impacts. The effects of different fertilisation strategies on soil biology and nitrogen (N) dynamics were investigated under field (farm site comparison), semi-controlled (lysimeter study) and controlled (incubation experiments) conditions by determining soil microbial biomass carbon (C) and N, enzyme activities (dehydrogenase, arginine deaminase, fluorescein diacetate hydrolysis), microbial community structure (denaturing gradient gel electrophoresis following PCR amplification of 16S and 18S rDNA fragments using selected primer sets) and N dynamics (mineralisation and leaching). The farm site comparison revealed distinct differences between the soils in microbial community structure, microbial biomass C (conventional > organic) and arginine deaminase activity (organic > conventional). In the lysimeter study, the soils were subjected to the same crop rotation (barley (Hordeum vulgare L.), maize (Zea mays L.), rape (Brassica napus L. ssp. oleifera (Moench)) plus a lupin green manure (Lupinus angustifolius L.) and two fertiliser regimes (following common organic and conventional practice). Soil biological properties, microbial community structure and mineral N leaching losses were determined over 2½ years. Differences in mineral leaching losses were not significant between treatments (total organic management: 24.2 kg N per ha; conventional management: 28.6 kg N per ha). Crop rotation and plant type had a larger influence on the microbial biomass, activity and community structure than fertilisation. Initial differences between soils decreased over time for most biological soil properties, while they persisted for the enzyme activities (e.g. dehydrogenase activity: 4.0 and 2.9 µg per g and h for organic and conventional management history, respectively). A lack of consistent positive links between enzyme activities and microbial biomass size indicated that similarly sized and structured microbial communities can express varying rates of activity. In two successive incubation experiments, the soils were amended with different rates of a lupin green manure (4 or 8t dry matter per ha), and different forms of N at 100 kg per ha (urea and lupin) and incubated for 3 months. Samples were taken periodically, and in addition to soil biological properties and community structure, gross N mineralisation was determined. The form of N had a strong effect on microbial soil properties. Organic amendment resulted in a 2 to 5-fold increase in microbial biomass and enzyme activities, while microbial community structure was influenced by the addition or lack of C or N substrate. Correlation analyses suggested treatment-related differences in nutrient availability, microbial structural diversity (species richness or evenness) and physiological properties of the microbial community. The findings of this thesis showed that using green manures and crop rotations improved soil biology in both production systems, that no relationships existed between microbial structure, enzyme activities and N mineralisation, and that enzyme activities and microbial community structure are more closely associated with inherent soil and environmental factors, which makes them less useful as early indicators of changes in soil quality.

The aim of this work was to assay the effects of previous history of organic amendment to soils in the field on the ability of those soils to mineralise mustard, a non-legume green manure. Soil and 15N labelled mustard mineralisation was followed in laboratory microcosms. Volatilised N was assayed by direct acid trapping of N in glass fibre disks, followed by direct combustion isotope ratio mass spectrometry. Animal manures, green manures and straw added to the soil in the field in the previous season, same season and for 7 years continuously did not significantly affect these soils' ability to mineralise mustard in microcosms. Nitrification and mineralisation were the dominant processes during the first 12 days of incubation. Volatilisation rates were 1000-fold lower than mineralisation or nitrification rates. Mustard N accounted for between 1-3% of the soil mineral N, whereas only a maximum of 0.01% of mustard N was volatilised over 24 days. Soils sampled at different times in the season decomposed mustard at similar rates at stimulated low spring temperatures. Nitrification rate was reduced 5-fold more than the mineralisation rate at 8oC. Straw incorporation for seven years did not affect the subsequent recovery of 15N enriched fertiliser or of 15N from labelled straw, by oil seed rape. 15N labelled fertiliser contributed up to 63% of the winter barley N. The labelled barley straw subsequently contributed 16% of the oil seed rape N in the absence of any applied fertiliser. Ploughing in straw in the autumn, in the absence of applied fertiliser had no yield penalty or effect on crop uptake, and may retain more mineral N in the upper soil layers, lessening the risk of leaching over the winter period. The results obtained here emphasise the importance of additions of organic materials to soil in supplying plant nutrients and minimising nutrient losses.

Agriculture has always been an important part in people’s daily life and has been developing over centuries with the development of technology and contributing to the rise of civilizations. Based on the production method, conventional and organic farming systems are currently the two main farming systems. The growing awareness of sustainability has forced people to think of how the future of these two farming systems would affect their sustainability performance. Swedish milk production is of high intensity and highly specialized. Swedish dairy farmers have highest milk yields in Europe, 9500 kilos per cow per year on average, and 73% of milk production takes place in the south of Sweden. The animals are kept indoors most of the year and manure is managed as slurry and removed to outdoor storage units every day. Most of the feedings are produced in Sweden, while some protein feed, especially soymeal and rapeseed meal, are imported from Brazil. Following the LCA methodology, this study aims to investigate the environmental impacts of conventional and organic milk production in Sweden, and then make a comparison between these impacts from the two systems. It also aims to find out the most influenced impact categories and the processes and activities with greatest impacts. Finally, it aims to give possible suggestions on the development of Swedish milk production systems. Methods applied in this study include a literature review of studies on milk production, especially LCA studies of milk production, and an LCA on Swedish milk production. Current LCA studies have made several improvements which are recommended in previous studies: a clear description of system boundary, a common functional unit, appropriate emission factors, and a range of impact categories. However, there are still some data gaps that need to be filled. The review shows that generally the functional unit is set to be 1 kg of energy corrected milk at farm gate, impact categories include energy use, land use, climate change, eutrophication, and acidification, cradle-to-gate boundary is used. Mass allocation, economic allocation and biological allocation are widely used. However, sensitivity analysis and uncertainty analysis are rarely conducted. LCA in this study shows that organic farming system does not have clear advantages over conventional system. Organic milk production has lower emissions in categories of CO, COD, HC, NOx, SO2, N, and P, and less use of fertilizer and pesticide. It has similar emissions of CH4, N2O, and NH3 with conventional milk production. But organic system has higher emission levels of CO2, NO3, and K, and higher land use and energy use. Looking at the corresponding ecological effects, the two systems do not have much difference in global warming, acidification, and photo-oxidant formation, while organic system has a higher eutrophication potential. To deal with environmental impacts, three types of strategies are discussed in this study. The first type concerns manure management. Improvement in manure management can reduce CH4 and N2O emissions and mitigate related ecological effects. The second one concerns milk yield, as CH4 from fermentation process, which is the main source of CH4, is lower at a higher yield. The last one is about transportation, including selecting origins of feed and transportation vehicles to reduce diesel use and replacing diesel with clean and renewable fuel.

South Africa (SA) is food secure on a national level, however citizens in rural and marginalised areas face household food insecurity due to lack of access to this food. South Africa has low fertility soils and scarce water resources. Climate change reports of unpredictable weather conditions will further exacerbate these challenges. The majority of the agricultural production methods in SA are industrialised and rely heavily on external inputs. Alternative agricultural production methods which are environmentally less taxing, are affordable and yield nutritious food, need to be investigated and adopted. A long-term trial investigating the differences in yields between conventional and organic farming systems was established at the NMMU George Saasveld campus. A baseline study preceded the cropping seasons to establish pre-treatment soil conditions before the two farming systems were be implemented. The trial was a randomized complete block design split into organic, conventional and control plots. In the first cropping season (summer) three crops cabbage (Brassica oleracea var. capitata), sweet potato (Ipomea batatas) and cowpea (vigna ungucuilata) were planted under the different treatments. Soil fertility changes after application of chemical and organic fertilizer were measured. Soil pH and phosphorus increased whilst potassium and soil carbon decreased from baseline levels. The organic plots were found to have higher soil pH, potassium and carbon, whilst P was higher in the conventional plots. The organic cabbages had a yield 12% lower than conventional cabbages, organic cowpeas were 51% lower than conventional cowpeas. Baboons damaged sweet potato plots before maturity. Broccoli (Brassica oleracea var. italica), radish (Raphanus sativa) and green pea (Pisum sativum) were planted in the second cropping season (winter). Organic broccoli yields were 51% lower than conventional broccoli, organic green peas were 18 % lower than conventional green peas. The organic radish yields were 36% lower than conventional yields and this was statically significant. The yield differences were statically significant between control and conventional cabbages (25%) and broccolis (68%). The results indicate that there is on average an initial 25% yield difference between organic and conventional farming systems. Similar studies have shown that the yield gap can be reduced within three to four years. This study presents preliminary results of trials that are to continue for ten years, during which time the yield differences may vary.

Organic farming is experiencing rather rapid development in Europe, including in Latvia. This could be rated from different aspects. The purpose of this article is to assess the economic indicators of the development of organic farming, linking them to conclusions stated in various studies in Latvia and other countries on the diverse economic, social and environmental impact of this type of farming, as well as potential problems. So, theoretical and empirical approaches are combined in this article. The different problems we can state as outcome of the research. The farms concentrate in areas with less favourable conditions for conventional farming. Also, large continuous areas under organic farming often leads to low production value per hectare and do not reach social goals.

Organic farming uses management practices that would avoid the use of chemical inputs and minimizes damage to the environment and wildlife. Thus we are brought significant restrictions on synthetic chemicals used in obtaining food products. The method involves different practices aimed at protecting the environment, maintaining and enhancing soil fertility, obtaining unpolluted and high quality agricultural products, and at last, promoting sustainable agricultural development. Romania has a great opportunity for organic farming as a result of natural conditions. However, Romania is located behind other EU or world countries. The present study shows the empirically based growth rate, of organic agriculture needed by Romania to reach in year 2025 the level of other countries. For comparison and calculations were considered France (one of the major players in the market of organic products) and Lithuania (that also has a well-developed organic agriculture). The results show that the current growth is not enough to overcome the first half of the top EU countries and requires an acceleration of this process of transformation into organic.

The paper presents the relationships of organic farming with sustainable development of agriculture and rural areas. The promotion of environmentally friendly agriculture and environmental protection are implemented within agri-environmental programs. The aim of these programs is to achieve sustainable rural development and preserve biodiversity. The goal of studies was to assess the sustainability of ecological agriculture at the level of an agricultural holding. Organic farming is perceived as a system that is most favorable from the perspective of environmental protection. Analysis was conducted on the basis of data from ecological farms in the Podlaskie voivodeship registered in the FADN system in 2014. Ecological indicators (share of cereals in crops, vegetation coverage of the soil throughout the year, stocking density, balance of organic substances, agricultural and environmental actions taken) as well as economic indicators: land profitability and productivity and profitability of labor, were accounted for. It was determined that the conditions of environmental sustainability were met with regard to the majority of ecological indicators. From the perspective of economic effects, organic farming achieved a positive financial result, but it was lower than in conventional farms. This result was achieved thanks to public subsidies for ecological production.
